2.2 Project Construction and Development Activities Infrastructure that is required to support the Project increase in ROM coal production would be progressively developed in parallel with ongoing mining operations at the Metropolitan Colliery. The Initial Development Schedule is attached as Appendix C1 and the key components that would be developed during the initial stages of the Project include: • Longwall mining machinery and electricity supply upgrades. • Upgrade of materials handling systems (Appendix C2) from approximately 650 tonnes per hour (tph) to approximately 1000 tph. • Upgrade of the CHPP (Appendix C3) to include a beneficiation circuit (to produce thermal coal) and to facilitate increased coal washing and production from approximately 400 tph to approximately 600 tph. • An additional (short-term) 50,000 tonne ( t) stockpile for coal rejects adjacent to a new backfill paste plant (approximately 75 tph) and goaf cavity injection system to dispose of excess coal reject material. Surface construction works would be undertaken intermittently over a period of up to five years generally during daytime hours up to seven days per week. For short periods additional mobile equipment would be required. 2.3 Current and Proposed Hours of Operation The existing Metropolitan Colliery and proposed project operating hours are summarised in Table 2.

Selected representative assessment locations for each receiver area are presented in Table 3. Local Environmental Planning zones are shown on the Local Zoning Plan (Appendix D2).
